From what I understand about furries, a lot of them do not have a species they stick to. Whether this be by choice or not differs. I think most furs that are undecided are a different kind of fur to those that are certain about what they are. But this is just how I view the furry realm - not really being a fur does help to see things differently, though I do understand that I may not have a clear view of things in the eyes of a fur, if you get what I mean. So, how does this effect you? Well, it's difficult to say, really. From personal experience, I've never had any problem knowing what I am. But what I would suggest to you is to think of it not that you are unsure of what creature you are, but that you are an individual, and are the only being in the world in the past, now, or in the future that lives, or will live the same life as you, and have your feelings, if you know what I mean. You may find that you, like a lot of furs, are a mix of more than one species. I think that's fine - it shows a mixture of personalities and feelings within one being, though you're probably more fortunate than myself, and be able to have them live together well without conflict - I'm sure many manage that. Anyway, I'm rambling on again. I hope I've made some sort of sense in this post. There must be a good point in it somehere.
